On August 20, 2019, the U.S. Environmental Protection Agency (EPA) published in the Federal Register final significant new use rules (SNUR) under the Toxic Substances Control Act (TSCA) for 145 chemical substances that are the subject of premanufacture notices (PMN).  84 Fed. Reg. 43266.  According to EPA, the chemical substances are subject to orders issued by EPA pursuant to TSCA Section 5(e).  The final SNURs require persons who intend to manufacture (defined by statute to include import) or process any of the 145 chemical substances for an activity that is designated as a significant new use by the rule to notify EPA at least 90 days before commencing that activity.  The required notification initiates EPA’s evaluation of the use, under the conditions of use for that chemical substance, within the applicable review period.  Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required by that determination.  The final SNURs will take effect October 21, 2019.

EPA notes that the final SNURs may also affect certain entities through pre-existing import certification and export notification rules under TSCA.  Chemical importers are subject to TSCA Section 13 import certification requirements.  Chemical importers must certify that the shipment of the chemical substance complies with all applicable rules and orders under TSCA.  Importers of chemicals subject to the SNURs must certify their compliance with the SNUR requirements. Any persons who export or intend to export a chemical substance that is the subject of the SNURs on or after September 19, 2019, are subject to the export notification provisions of TSCA Section 12(b) and must comply with export notification requirements.

The U.S. Environmental Protection Agency (EPA) announced on August 16, 2019, that it is opening a public comment period for manufacturer requests for the risk evaluations of diisodecyl phthalate (DIDP) and diisononyl phthalate (DINP), two chemicals used in plastic production.  EPA notes that the manufacturer-requested risk evaluations “are among the first such evaluations of this kind to be requested” under the Toxic Substances Control Act (TSCA).  EPA is also taking public comments on additional conditions of use it identified to include in the risk evaluations.  Upon publication of the Federal Register notices, comments may be submitted to Docket ID EPA-HQ-OPPT-2018-0435 for DIDP and Docket ID EPA-HQ-OPPT-2018-0436 for DINP for 45 days.  EPA encourages comments on any information not included in the manufacturer requests that commenters believe would be needed to conduct a risk evaluation.  EPA also welcomes any other information relevant to the proposed determinations of the conditions of use, including information on other conditions of use of the chemicals than those included in the manufacturer requests or in EPA’s proposed determinations.  After the comment period closes, EPA will review the comments and within 60 days either grant or deny the requests to conduct risk evaluations.  If these requests are granted, the manufacturers would be responsible for half the cost of the risk evaluations.  More information is available in our August 19, 2019, memorandum, "EPA Begins Comment Period on Manufacturer Requests for Risk Evaluation of DIDP and DINP, and Identifies Additional Conditions of Use."

On August 13, 2019, the U.S. Environmental Protection Agency (EPA) released the list of 20 chemical substances that it proposes to designate as low-priority substances for which risk evaluation under the Toxic Substances Control Act (TSCA) is not warranted at this time.  EPA’s August 15, 2019, proposed rule provides a summary of the approach used by EPA to support the proposed designations, the proposed designations for each of the chemical substances, and instructions on how to access the chemical-specific information, analysis, and basis used by EPA to make the proposed designation for each chemical substance.  84 Fed. Reg. 41712.  EPA published its Approach Document for Screening Hazard Information for Low-Priority Substances Under TSCA (Approach Document), which describes the literature review process for the information used in the screening review for each proposed low-priority chemical substance.  Comments on the proposed designations and on EPA’s Approach Document are due November 13, 2019.

Commentary

As expected, EPA has formally proposed as low-priority substances the 20 substances that EPA proposed in March as potential low-priority substances.  Stakeholders will have 90 days to comment on whether EPA has met the statutory obligation to have information “sufficient to establish” that the substances do not meet the standard for high-priority substances (that the substances may present an unreasonable risk).  Comments were filed on only seven of the 20 substances initially identified as low priority, and all comments supported the designations as low priority. 
 
More information is available in our August 14, 2019, memorandum, “EPA Proposes to Designate 20 Chemical Substances as Low-Priority Substances.”

Section 5(g) of the Toxic Substances Control Act (TSCA) requires the U.S. Environmental Protection Agency (EPA) to publish a statement of its findings after its review of TSCA Section 5(a) notices when EPA makes a finding that a new chemical substance or significant new use is not likely to present an unreasonable risk of injury to health or the environment.  On August 12, 2019, EPA published a statement of its findings for June 2019.  84 Fed. Reg. 39828.  EPA notes that such statements apply to premanufacture notices (PMN), microbial commercial activity notices (MCAN), and significant new use notices (SNUN) submitted to EPA under TSCA Section 5.  In the Federal Register notice, EPA provides the following information (to the extent that such information is not claimed as confidential business information (CBI)) on the PMNs, MCANs, and SNUNs for which, during this period, EPA has made findings under TSCA Section 5(a)(3)(C) that the new chemical substances or significant new uses are not likely to present an unreasonable risk of injury to health or the environment:  EPA case number assigned to the TSCA Section 5(a) notice; chemical identity (generic name, if the specific name is claimed as CBI); and website link to EPA’s decision document describing the basis of the “not likely to present an unreasonable risk” finding made by EPA under TSCA Section 5(a)(3)(C).

The U.S. Environmental Protection Agency (EPA) released on August 9, 2019, the draft risk evaluation for 1-bromopropane (1-BP), the fourth of the first ten chemicals undergoing risk evaluation under the amended Toxic Substances Control Act (TSCA).  EPA made the following initial determinations on risk:

  • Unreasonable risks to workers, occupational non-users, and consumers under certain conditions of use.  EPA notes that these initial determinations are not its final determinations on whether 1-BP presents unreasonable risks under the conditions of use.  EPA states that it will use feedback received from the public and peer review processes to inform the final risk evaluations.
  • No unreasonable risk to the environment.  For all the conditions of use included in the draft risk evaluation, EPA found no unreasonable risks to the environment from 1-BP.

EPA states that these initial determinations may change as its evaluation becomes more refined through the public and peer review process.  The draft risk evaluation, including initial risk determinations as to whether the chemical under the conditions of use presents an unreasonable risk to human health or the environment, is not final.  If unreasonable risk is found for one or more conditions of use in a final risk evaluation, EPA will propose actions to address those risks within the timeframe required by TSCA.

The TSCA Science Advisory Committee on Chemicals (SACC) will peer review the draft risk evaluation at a September 10-12, 2019, meeting.  EPA will hold a preparatory virtual meeting on August 21, 2019, to discuss the scope and clarity of the draft charge questions to SACC.  EPA requests comments on the draft risk evaluation by August 30, 2019, to allow SACC time to review and consider them before the peer review meeting.  Comments received after August 30, 2019, and prior to the end of the oral public comment period during the meeting will still be provided to the SACC for their consideration.  EPA will continue to accept comments on the draft risk evaluations until October 11, 2019.  EPA will consider all comments received on the draft risk evaluations by the October 11, 2019, deadline when developing the final risk evaluation.  More information is available in our August 12, 2019, memorandum, "EPA Draft Risk Evaluation for 1-BP Finds Unreasonable Risks to Workers, Occupational Non-Users, Consumers, and Bystanders under Certain Specific Uses."

On July 29, 2019, the U.S. Environmental Protection Agency (EPA) published in the Federal Register its proposed rule intended to reduce exposures to certain chemicals that are persistent, bioaccumulative, and toxic (PBT).  84 Fed. Reg. 36728.  EPA identified five chemicals pursuant to Section 6(h) of the Toxic Substances Control Act (TSCA):  decabromodiphenyl ether (DecaBDE); phenol, isopropylated phosphate (3:1) (PIP (3:1)), also known as tris(4-isopropylphenyl) phosphate; 2,4,6-tris(tert-butyl)phenol (2,4,6-TTBP); hexachlorobutadiene (HCBD); and pentachlorothiophenol (PCTP).  The proposed rule would restrict or prohibit manufacture (including import), processing, and distribution in commerce for many uses of all of the chemicals except HCBD, for which EPA is proposing no regulatory action.  For the other four chemicals, the proposed rule includes recordkeeping requirements, as well as additional downstream notification requirements for PIP (3:1).  Comments are due September 27, 2019.  Our June 24, 2019, memorandum, “EPA Publishes Proposed PBT Chemicals Rule under TSCA,” provides a detailed review and analysis.

In the March 27, 2019, Federal Register, the U.S. Environmental Protection Agency (EPA) issued its final regulatory rulemaking that prohibits the manufacture (including import), processing, and distribution of methylene chloride for consumer paint and coating removal. 84 Fed. Reg. 11420.  See Bergeson & Campbell, P.C.’s memorandum, “EPA Bans Consumer Sales of Methylene Chloride Paint Removers, Seeks Comment on Program for Commercial Uses.”
 
Starting on August 26, 2019, which is 90 days after the effective date of the final rule, a company that manufactures, processes, or distributes in commerce methylene chloride is required to provide notification to downstream users of the consumer use paint remover restrictions via Safety Data Sheets (SDS).  We write to emphasize that this notification requirement applies to all manufacturers, processors, or distributors of methylene chloride and is not limited only to those companies engaged with paint remover products.  The EPA rulemaking provides the following specific text that must be included in the SDS:

  • SDS Section 1.(c):  “This chemical/product is not and cannot be distributed in commerce (as defined in TSCA section 3(5)) or processed (as defined in TSCA section 3(13)) for consumer paint or coating removal.”
     
  • SDS Section 15:  “This chemical/product is not and cannot be distributed in commerce (as defined in TSCA section 3(5)) or processed (as defined in TSCA section 3(13)) for consumer paint or coating removal.”

More information is available in our July 22, 2019, memorandum, “Communication and Recordkeeping Requirements Related to EPA Ban on Consumer Use Paint Removers Containing Methylene Chloride Go in Effect on August 26, 2019.”
